If you're looking for ghosts in Providence, RI, you really don't need to look any further than the Biltmore Hotel. The Biltmore was added to the National Register of Historic Places in 1977 and is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation. Oh, and it was named “America’s Most Haunted Hotel” in 2000 by the American Hotel & Lodging Association.
